DANIEL MOALLISTEB, OF ST. LOUIS, MO., ASSIGNOB OF ONE-HALF TO WILL- IAM LEFMANN AND JULIUS F. WV. LEFMANN, BOTH OF SAME PLACE.

PEDESTAL AND AXLE-BOX FOR CARS.

SPECIFICATION forming part of Letters Patent No. 350,010Jdated September 28,1886.

Application filed May 13, 1886. Serial No. 202.089.

To all whom it may concern:

Be it known that I, DANIEL MoALLIsTER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Pedestals and Axle-Boxes for Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which re Figure 1 is a vertical longitudinal section of the improvement at l 1, Fig. 3, except that one of the hangers is shown in side elevation. Fig. 2 is a side elevation of the improvement. Fig. 3 is a transverse section of the improvement at 3 3, Fig. 2, except that the hanger is shown in elevation. Fig. 4 is a perspective View of the inverted cup of the hanger. Fig. 5 is a perspective view of the stud-collar.

The improvement relates to the manner of .20 connecting the car-body to the axle-boxes; and it consists in trunnions on the axle-box, on which are suspended hangers carrying coiled springs, on which are supported bellformed cups or cases, having movement on the hangers and connected to the pedestal by studs or other suitable connection.

A is part of one of the sill-timbers of the car body, to which the pedestal B is con nected in any suitable manner-screw-bolts G 0 and nuts 0 being shown for this purpose, the bolts passing through the sill and the top of the pedestal. The pedestal B is formed with side plates, B, having flanges B, horizontal plate 13*", end plates,B" and journal-bearings 3 5 B", the sill seating between the flanges on to the horizontal plate. The sides B of the pedestal have apertures B to receive the axle-box D, which has free transverse movement in the apertures, and for this purpose fits easily be tween the guide-cheeks B at the sides of the apertures.

E are trunnions, forming part of a trunnion-block, E, cast on or attached to the box, and extending parallel with the sill A.

F are the hangers, which consist of eyebolts, whose eyes F fit on the cylindrical parts or trunnions. Upon the lower ends of the hanger-bolts are screwed nuts G, which are formed on top as cups G, upon which rest the lower ends of the coiled springs H. The

cups G may be in one piece with the nuts, or may be distinct pieces. Upon the upper ends (No model.)

of the springs bear the inverted cups I, which have the shape of a bell with an outturned flange at the lower edge, upon which rests a stud, ring, or collar, J, whose studs J have bearing at b in the journal-bearings B of the sides of the pedestal, and are held in their bearings by caps K. The holes i in the cups I (through which the hauger-bolts pass) are elongated in a transverse direction, so as to allow the bolt side movement in the holes as the car sways from side to side, and gives.

transverse movement to the axle-box between the cheeks B. The interior diameter of the lower part of the bearing-cup is so great as to allow the end of the hanger-bolt side movement therein.

As a modification, the studs J may project in a line parallel with the trunnions E, so that the bearing-cups I may oscillate on the studs in the side swaying of the car, in which case the elongation of the hole i would not be necessary, as the cup would oscillate with the hanger-bolt. This position of the studs is clearly indicated in dotted lines at J in Figs. 1 and 3.

The cups I and the ring or collar J may obviously be made in one piece, or the studs J cast upon the cups, as seen in dotted lines at J2, Fig. 4.

I claim as my invention- 1. A pedestal comprising side plates, B, having flanges B, horizontal plate B end plates, B, apertures B cheelcplates B, andjournal-bearings Bflsubstantially as shown and described.

2. An axle-box, D, formed with trunnionblock E and trunnions E, and a pedestal, B, in combination with spring-connections between the trunnions and the base of the pedestal, substantially as shown and described.

3. The combination of the pedestal B, axlebox D, formed with trunnion-block E, having trunnions E, eyebolts F, forming hangers hinged to the trunnions,having nuts G, springs supported on the nuts, and inverted bells I, supported on the springs, having bearingstuds, substantially as shown and described.
